Abstract

A discharge means of a container for pulverulent or granular material has a conical outlet (1) into which compressed air can be introduced through a porous replaceable part (4) for increasing the fluidity and slidability of the loose material. A ring (22) arranged at the lower end of the replaceable porous part (4) is secured in position by braces (48) projecting into the interior of the outlet (1) and releasably secured by means of a securing device (49). <IMAGE>

Description

SPECIFICATION Discharge means of a container for pulverulent or granular loose material This invention relates to a discharge means of a container for pulverulent or granular loose material with an outlet tapering conically downwards to the narrow cross-section of a connecting piece for a feedpipe, at least the hopper-shaped inner outlet face being made from a porous foil material through which can be passed compressed air for increasing the fluidity and slidability of the loose material and being held as a replaceable part at least on the upper hopper periphery and being reinforced in annular manner for this purpose and being secured between a flange face of the container and an opposite flange face of the outlet, whilst the lower inner edge of the replaceable part being increasingly securely held in the outlet by a ring.Such a discharge means is disclosed, by way of example, in British Patent Specification No. 2065087A.
In the case of such a construction the lower edge of the replaceable part is held by a threaded ring. This threaded ring must have a relatively large diameter and it is relatively complicated and costly to produce the thread.
The present invention aims to simplify the securing of the lower edge of the replaceable part, so that said part can be rapidly replaced with limited effort and expenditure on fitting.
According to the invention, the replaceable part is secured above the ring by braces projecting into the interior of the outlet and secured by a securing device.
In a constructionally particularly advantageous manner, at least three braces are provided which converge in pyramid-like manner into the outlet and are interconnected at their convergent ends at which location the securing device is engaged.
In order to as far as possible prevent damage to the replaceable part, the ends of the braces co-operating with the ring of the replaceable part are interconnected by a securing ring.
Advantageously, the securing means can comprise further braces projecting into the outlet and co-operating by means of at least one securing thread with the other braces, said further braces being anchored to the outlet. Advantageously, the further braces are positioned approximately parallel to the pyramidally arranged braces and are interconnected at their converging ends, the securing thread being provided there on an extension.
In turn the converging ends of the braces can carry a securing tube in space-saving manner and on this engages the securing device. Advantageously for this purpose the extension of the additional braces is passed through the securing tube and a clamp nut, which can be screwed onto the extension is supported on the upper end of the securing tube.
For rapid assembly and disassembly it is particularly advantageous for the ends of the further braces freely anchored at the outlet to be suspendable and detachable in cover plates of the outlet. For this purpose they can be swung in bent manner into openings in the cover plates, particularly if the further braces are constructed in one piece with the extension to form a structural unit, which considerably facilitates handling. In the same way the braces, securing ring and securing tube can be constructed in one piece as a constructional unit.
The invention will now be further described by way of example, with reference to the drawings, in which: Figure 1 is a partial cross-section through one embodiment of a discharge means according to the invention; and Figure 2 is a plan view of the lower part of the discharge means in the direction of the arrow II of Fig. 1 and on a larger scale.
The discharge means has a hopper-shaped, sheet metal outlet 1 screwed by means of Ubolts 40 e.g. to the discharge opening of a transportation vehicle silo. By means of the Ubolts 40, a flange 2 of the silo container is tightly secured to the opposite flange 5 of the outlet 1, whilst interposing an all-round edge 3 of a replaceable part 4.
The replaceable part 4 is adapted to the hopper shape of the outlet 1 and is made from an air-permeable fabric. The inside of the part 4 forms a discharge face and by blowing compressed air into the space between the casing wall 6 and the replaceable part 4, the not shown conveyed material is fluidized by compressed air and loosened in this way it can flow out through an exit 9 in the lower edge 10 of replaceable part 4 and through a connecting piece 11 into a feedpipe 42.
For securing the replaceable part 4 on the lower edge 10 is incorporated a ring 22 engaging in fitting manner on the lower flanged ring of the outlet 1. This in fact takes place with a limited spacing with respect to a cylindrical face 43, which is made sufficiently long to ensure reliable securing of the replaceable part 4 in the downwards direction of the outlet 1.
To prevent excessive bulging of the porous part 4 through the delivery air blown in through the connecting fitting 12, two stiffening rings 44, 44' are distributed over the hopper length and via U-bolts 45, 45' distributed over the periphery are held on the part 4 by screws 46.
For the securing of the part 4, a securing ring 47 is arranged in easily removable manner above the ring 22, and is held at its lower end by braces 48 running pyramidally into the interior of the hopper, where they terminate at a securing tube 49. There are only three braces 48 to ensure that the material outflow is impeded to the minimum. The securing ring 47, braces 48 and securing tube 49 are constructed as a constructional unit.
Below the rings 22 and 47, two cover plates 50 with in each case one opening 51 are welded into the outlet 1. The end of in each case a further brace 52 is suspended in each of the openings 51 and for this purpose said brace ends are bent in the manner shown in Fig. 2. The further braces 52 are directed approximately parallel to the braces 48 and their ends are combined with an extension 53, which is in turn passed through the securing tube 49 and has a thread 54 for a clamp nut 55 supported at the top of the securing tube 49. The further braces 52 and extension 53 also form a constructional unit which can easily be removed from the outlet 1. Thus, the replaceable part 4 can be easily and rapidly removed with limited effort and expenditure if it has to be cleaned or if it is not in use. In the case of readily flowing materials, the connecting fitting 1 2 can be sealed by a corresponding insert.
